To all you Brits!!!

[Mike, Lord of the Spammers!]

They have one with 20,000 rounds through it with no cleaning and no stoppages.

Come along way from the jungles of Veitnam then

Well you got to remember that during Vietnam the rifles had no cleaning kits, Forward assist, and the chamber and barells were not chrome lined. Also they changed the powder to make it burn better.


God I got to get a hobby.

Well the fact that i knew that too means I'm a sad case too , I've even read the letter read out in congress

[hawkchucker]

Well we both then need to got out more.

Maybe we should just step away from the computer...just for a few minutes at first

[hawkchucker]

OK i did it and it does not work.

[J-sews]

For my money I think we should have bought the Steyr AUG instead, not that I'm trying to imply that I know more than those in power of course

I liked the Steyr AUG. Never handled one of course, but I always thought it looked cool.

Yah it actually is really sweet. the inner guts all really changed in it, It is no longer gas operated. so it runs cooler. they retain the shape of the M4 so less training time is needed during the transition. it also since now a blowback not gas runs also cleaner.

To be "technical"(well, a little) the HK 416 is still gas operated. The big difference is that the M16/M4 use direct impingement where the gas from the barrel is channeled directly back to push back the bolt in the chamber. In the HK 416 the gas from the barrel is channeled into a piston, the piston then hits a rod which is what pushes the bolt back. Since the bolt and chamber isn't directly getting hot gases(and crap) from the barrel it's a lot cleaner.

The advantage of the direct impingement system is that with fewer moving parts the potential accuracy is better and theoretically less chance of parts breaking. Although most modern day assault rifles use the gas piston method and it has proven to be durable enough for combat.

Now this is a very simplistic overview of it but it does explain the major difference.

So, has HK abandoned its famous roller-lock system used on HK91, HK92, MP5, and even some of the HK pistols?

Some experts claim the HK roller-lock is about the finest system ever devised for military rifles.

The basic gas-piston system is very common - has been used since the 1930s for military rifles.

Yeah but the roller block is hugely expensive to produce, and if you've got to re-equip a substantial proportion of an army, every saving help's

On a side note, HK reluctance to depart from the roller block has got to be largely responsible for the eventual take over by BAe, as not many armies could afford there weapons

[hawkchucker]

Rollerlock aint a HK invention.

Anyone know the pistol that started it all?

Wasn't it that steyr pistol around the 1900

[NutSAK]

I guess I don't.  Are you talking about roller-delayed blowback as in the HK G3 or P9 pistol, or roller-locked recoil, as in the MG42 design?

[Dunc]

Just remember it was the British fighting the British.  Americans did not exist...in fact the first Presidents were born and bred in England.


Flash

Theres a joke about friendly fire in there somewhere

Dunc

[hawkchucker]

Nope the true roller lock came out with the Checz CZ 52 pistol.

It actually was also a true magnum using a stepped down case. 2500 ft per sec for a pistol.

The HK system that ringzero is referring to (in the MP5 and G9 pistol) isn't a roller-locked recoil system as the CZ-52 and MG42 use.  The HKs use a roller-delayed blowback system.  In the blowback system, the barrel is stationary (no recoil) and the action of the bolt is delayed by the rollers.  In the recoil sytem, the barrel travels part of the way back with the slide, until it is disengaged from the slide after the rollers enter the recesses.

The MG42 used the roller-locked recoil system 10 years prior to when the CZ-52 entered production.

Thanks guy's, there are still huge gaps in my firearms knowledge, as there's not been much reason to get into them over here

[NutSAK]

there's not been much reason to get into them over here

 

That would make me angry, or at least quite frustrated.  I'm fortunate that I live in a state that is very lenient when it comes to gun laws.  If I wasn't so fortunate I think I would consider moving but, of course, I would not have to consider another country.

You have my sincere condolences .

It is a shame as I was quite an active rifleman until I hit 18, I't just started to shoot pistols when the Dunblane tragidy occured

Without getting into excruciating detail of the firearms laws in the UK, I do have one question.  Are you able to hunt with firearms?

EDIT:  Nevermind.  I just read up on UK laws and the Hungerford and Dunblane masscres.  So, it appears that you're limited to blackpowder and shotguns with 24" minimum bbl length and maximum 2+1 cartridge capacity.

No you can still hunt with rifle's mate

Good to hear!
